Title: Primary key field as instance variable in BMP entity beans

Murali,

 

see the thread "pedstore: storing the userid" on this mailing list. The outcome was to get the primary key always by "context.getPrimaryKey()" and not store it as an instance variable, because the bean instance will be reused for different entities and therefore the primary key of the object will change, if you don't want to track the swapping instances, you'll be better of getting it always from the context.

Subject: Primary key field as instance variable in BMP entity beans

Hi,

Is it mandatory to have an instance variable for primary key field in a bean managed entity bean? If it is mandatory, do I need to set that instance variable to context.getPrimaryKey() in ejbActivate () method and set it to null in ejbPassivate()?

Thanks,
Murali.
